Mix saltwash into any paint of choice, until mixture has a thick "icing like" consistency.
Apply saltwash using a glob like technique, pulling up the peaks of your mixture.
Once the saltwash layer begins to dry, gently knock down the peaks with gentle brush strokes.
After saltwash layer is completely dry, apply a top coat of paint. This layer will have no saltwash added to the paint.
Once top coat is completely dry, sand to reveal the saltwash layers.
Congrats! You achieved an amazing layered and weathered worn look!
